What determines (in)effective post-competition parent-child interactions in British Tennis? A conversation analysis of car journeys home Sutcliffe et al. (2025) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/abs/pii/S1469029225000391 A study of 13 parent-child pairs with audio and video recordings of actual car journeys home after tennis matches. Found that children disengaged when parents led with performance critique, but opened up and had productive conversations when they were allowed to initiate the discussion themselves.
Parent and child car-ride interactions before and after sport competitions and practices: Video analysis of verbal and non-verbal communication Tamminen et al. (2021) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/abs/pii/S1469029221002132 Analysed 98 video recordings across 28 parent-child pairs (30 hours of footage). Found that parents frequently jumped in before their child had finished responding, and that open, reflective questions were rarely asked. One of the most detailed observational studies of what actually happens in the car.
The role of parents in the motivation of young athletes: a systematic review Frontiers in Psychology (2023) https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2023.1291711/full A large-scale review of 29 studies examining how parental behaviour shapes young athletes’ motivation, confidence, and long-term engagement. Found that autonomy-supportive parenting, giving children space to lead and decide, consistently produced stronger psychological outcomes than directive or controlling approaches.
Parental Involvement in Youth Sports: A Phenomenological Analysis of the Coach–Athlete–Parent Relationship MDPI Sports (2025) https://www.mdpi.com/2673-995X/5/3/81 A qualitative study involving athletes, parents, and coaches from the same football club. Found that non-intrusive encouragement and child-led post-competition dialogue were among the most important factors in helping young athletes manage pressure and find meaning in their sport.
Understanding Adolescent–Parent Interpersonal Relationships in Youth Sports: A Mixed-Methods Study PMC / PubMed Central (2018) https://pmc.ncbi.nlm.nih.gov/articles/PMC6027542/ A mixed-methods study of 648 adolescent athletes examining the role of trust, communication, and emotional support in the parent-athlete relationship. Athletes consistently identified trust and being heard as the most important elements of parental support in sport.
The role of personality traits in athlete selection: A systematic review Xu & Hao (2025) — Personality and Individual Differences https://www.sciencedirect.com/science/article/pii/S0001691825007917 A systematic review finding that psychological factors consistently outperform physical assessments in predicting long-term athletic success. Conscientiousness, adaptability, and emotional stability emerged as reliable predictors of elite achievement across multiple sports and cultures.
Differences in the Psychological Profiles of Elite and Non-elite Athletes Frontiers in Psychology (2021) https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2021.635651/full Compared the psychological traits of elite and non-elite athletes and found that psychological factors including self-efficacy and emotional intelligence can predict future sporting success even at an early stage of athletic development, often more reliably than physical ability.
Relative Age Effect in Sports: Talent Identification, Performance, and Fair Practices Frontiers in Sports and Active Living (2025) https://www.frontiersin.org/journals/sports-and-active-living/articles/10.3389/fspor.2025.1748381/abstract Reviews four decades of research showing that athletes born earlier in the selection year are consistently overrepresented in development pathways, not because of greater talent, but because of physical maturity. Argues that current talent identification systems systematically overlook late developers with genuine long-term potential.
Relative age effect and performance in elite youth male basketball Scientific Reports / Nature (2023) https://www.nature.com/articles/s41598-023-31785-4 A study of 678 youth basketball players across six tournaments found that more players born in the first quarter of the year were selected into elite programs, despite birth quarter having no significant effect on individual performance. Highlights how selection bias can remove talented late developers from pathways entirely.
The influence of the five-factor model of personality on performance in competitive sports: a review PMC / PubMed Central (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC10756238/ A broad review of how personality traits relate to sporting success. Found that conscientiousness, emotional stability, and openness to experience are consistently associated with higher performance, while raw physical talent measures are weaker long-term predictors of who reaches the elite level.
Using self-determination theory to explain sport persistence and dropout in adolescent athletes Calvo et al. (2010) — PubMed / National Library of Medicine https://pubmed.ncbi.nlm.nih.gov/20977017/ A study of 492 soccer players aged 13 to 17 found that sport dropout was directly predicted by higher levels of external regulation and lower satisfaction of autonomy needs. Athletes who participated primarily because of outside pressure were significantly more likely to quit than those with internally driven motivation.
Sports motivation: a narrative review of psychological approaches to enhance athletic performance Frontiers in Psychology / PMC (2025) https://pmc.ncbi.nlm.nih.gov/articles/PMC12358434/ A review of 97 studies published between 2001 and 2024 finding that intrinsic motivation consistently produces more sustained athletic performance and long-term commitment than extrinsic motivation. External pressure was found to generate short-term compliance but lacked lasting influence on genuine engagement.
Self-determination theory based instructional interventions and motivational regulations in organised physical activity: A systematic review and meta-analysis ScienceDirect (2022) https://www.sciencedirect.com/science/article/pii/S1469029222001169 A meta-analysis of 38 studies covering 12,457 participants demonstrating that autonomy-supportive environments increase intrinsic motivation while simultaneously reducing external regulation. Provides a clear empirical case for why building the conditions for internal motivation outperforms enforcement as a long-term strategy.
Exploring the Dynamics of Athletes’ Enjoyment and Self-Determined Motivation in Youth Football: A Longitudinal Perspective PMC / PubMed Central (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC10924548/ A longitudinal study in youth football finding that players who found joy in the game itself, rather than in external rewards or pressure, were more likely to sustain engagement and report positive experiences over time. Highlights the role of autonomy-supportive environments in building durable motivation.
Creating the conditions for psychological safety and its impact on quality coach-athlete relationships ScienceDirect (2022) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/pii/S146902922200231X Found that athletes who felt psychologically safe were more likely to engage in open, honest communication with coaches, admit mistakes, and raise concerns without fear of humiliation. Athletes in unsafe environments developed compliance behaviours instead of genuine engagement with feedback.
Investigating the impact of coach behaviours and coach-athlete relationships on psychological safety Taylor & Francis (2024) https://www.tandfonline.com/doi/full/10.1080/1612197X.2024.2369717 Examines how supportive versus controlling coach behaviours shape the presence or absence of psychological safety. In psychologically safe environments, athletes were more likely to share ideas, ask questions, seek feedback, take ownership, and be accountable for their own development.
Psychological dynamics shaping performance perception in athletes: the influence of coaching behaviours, psychological safety, self-efficacy, and resilience PMC / PubMed Central (2025) https://pmc.ncbi.nlm.nih.gov/articles/PMC12866403/ A structural model study showing that supportive coaching behaviours directly predict psychological safety, which in turn improves self-efficacy and motivation. Found that open dialogue and non-punitive feedback are central to environments where athletes can genuinely develop.
Athletic Identity in Youth Athletes: A Systematic Review of the Literature PMC / PubMed Central (2021) https://pmc.ncbi.nlm.nih.gov/articles/PMC8305814/ A systematic review finding that when an athlete’s self-esteem rises and falls with their performance outcomes rather than being held independently, it creates vulnerability to anxiety, burnout, and performance fragility. During adolescence, an exclusive athletic identity can interfere with healthy identity formation more broadly.
Performance-based self-esteem and athlete-identity in athlete burnout: A person-centred approach ScienceDirect (2018) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/abs/pii/S146902921730818X A study of 448 Swedish junior athletes found that those with high performance-based self-esteem were significantly more likely to fall into high burnout profiles, while those with a strong but non-contingent athletic identity were more protected. One of the clearest research demonstrations of the difference between identity and worth being tied to results.
Sleep Optimization in the Young Athlete ScienceDirect (2024) — Current Sports Medicine Reports https://www.sciencedirect.com/science/article/pii/S2768276524001743 A clinical review establishing that young athletes commonly suffer from both acute and chronic sleep deprivation, with links to increased injury rates and decreased athletic and neurocognitive performance. Sleep extension consistently improved speed, reaction time, accuracy, alertness, and overall wellbeing.
Sleep and Athletic Performance: Impacts on Physical Performance, Mental Performance, Injury Risk and Recovery, and Mental Health PMC / PubMed Central (2023) https://pmc.ncbi.nlm.nih.gov/articles/PMC9960533/ A comprehensive review covering how sleep deprivation impairs reaction time, motor skill consolidation, decision making, and recovery. A basketball sleep extension study found that increasing average sleep from 7.5 to 10.25 hours produced measurable improvements in reaction time, sprint times, and shooting accuracy.
Being a right parent: a narrative review of the theory and practice of parental involvement in sport parenting PMC / PubMed Central (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC11190379/ Reviews the evidence on what helpful versus unhelpful parental involvement looks like after difficult performances. Found that parents who provide emotional presence and reframe setbacks constructively contribute to resilience, while those who prioritise performance correction over emotional support create psychological stress.
A grounded theory of positive youth development through sport based on results from a qualitative meta-study PMC / PubMed Central (2016) — International Review of Sport and Exercise Psychology https://pmc.ncbi.nlm.nih.gov/articles/PMC5020349/ One of the most-cited papers establishing that sport participation on its own does not produce reliably positive developmental outcomes. Character qualities like resilience, discipline, and leadership emerge from specific environmental conditions, adult relationships, and deliberate life skills development, not from the act of competing itself.
Positive youth development through sport: What works, under what circumstances, for whom? ScienceDirect (2025) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/abs/pii/S1469029225001165 A major review addressing what actually produces positive developmental outcomes in youth sport. Concludes that coaching behaviours, motivational climate, and the quality of adult-youth relationships are the active ingredients, not competition itself.
Sport specialization and burnout symptoms among adolescent athletes Taylor & Francis (2025) https://www.tandfonline.com/doi/full/10.1080/02673843.2025.2460626 A study of 169 adolescent athletes finding that those who specialised in a single sport showed significantly higher burnout scores than non-specialised peers, with links to emotional exhaustion and reduced sense of accomplishment.
Changes in Sports Participation, Specialization, and Burnout from 7th to 12th Grade: Final Results from a 6-Year Longitudinal Study PMC / PubMed Central (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC10916788/ A six-year longitudinal study finding that early specialisation is not a prerequisite for elite-level performance, and that athletes who participated in multiple sports in early-to-mid adolescence were more likely to go on to play at national elite level than those who specialised early.
AOSSM Early Sport Specialization Consensus Statement American Orthopaedic Society for Sports Medicine https://ncaaorg.s3.amazonaws.com/ssi/injury_prev/SSI_AOSSMEarlySportSpecializationConsensusStatement.pdf The formal position statement from orthopaedic sports medicine specialists concluding there is no evidence that early sport specialisation benefits young athletes in most sports, and that it increases risk of overuse injury and burnout. Recommends multi-sport participation until physical maturation.
Pre-Event Self-Efficacy and Sports Performance: A Systematic Review with Meta-Analysis PMC / PubMed Central (2023) https://pmc.ncbi.nlm.nih.gov/articles/PMC10675036/ A meta-analysis confirming self-efficacy as a consistent predictor of athletic performance, with mastery experiences identified as the most authentic and influential source of genuine confidence. Establishes that believing you can do something is most powerfully built through the lived experience of having done difficult things, not through verbal encouragement alone.
Self-Efficacy in High-Performance Sports: A Systematic Review and Meta-Analysis PMC / PubMed Central (2025) https://pmc.ncbi.nlm.nih.gov/articles/PMC12352364/ A systematic review of interventions to build self-efficacy in sport. Found that confidence built through achievement experiences produces more durable and performance-relevant belief than confidence built through other sources, with practical implications for how coaches and parents structure the development environment.
Achievement goal perspectives, perceptions of the motivational climate, and sportspersonship: individual and team effects ScienceDirect (2004) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/abs/pii/S1469029203000694 A large meta-analytic review covering 34,156 participants finding that perceptions of a task-involving climate were consistently associated with perceived competence, intrinsic motivation, positive affect, and better performance. Perceptions of an ego-involving climate were associated with extrinsic regulation, negative affect, and perfectionism.
Task-Involving Motivational Climate and Enjoyment in Youth Male Football Athletes: The Mediation Role of Self-Determined Motivation PMC / PubMed Central (2023) https://pmc.ncbi.nlm.nih.gov/articles/PMC9966829/ Demonstrates that a task-involving climate created by coaches supports self-determined motivation and enjoyment in young athletes. A controlling, ego-involving environment was associated with non-self-determined motivation and reduced engagement over time.
A scoping review of longitudinal studies of athlete burnout Frontiers in Psychology (2025) https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2025.1502174/full A longitudinal review establishing the three-stage progression of athlete burnout: physical and emotional exhaustion, reduced sense of accomplishment, and sport devaluation. Found that sport devaluation, the loss of meaning and connection to the sport, tends to emerge later in the burnout process and is the most psychologically significant and hardest to reverse.
A multi-sample examination of the relationship between athlete burnout and sport performance ScienceDirect (2024) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/pii/S1469029224001584 Across three samples totalling hundreds of athletes, reduced sense of accomplishment and sport devaluation were both found to negatively predict competition performance. Emotional exhaustion alone was not predictive of performance decline, making the later stages of burnout the most important to identify early.
Emotion Regulation and Mental Health in Young Elite Athletes PMC / PubMed Central (2025) https://pmc.ncbi.nlm.nih.gov/articles/PMC12473469/ A study of young elite athletes finding that expressive suppression (inhibiting outward emotional expression) is consistently associated with poorer mental health outcomes, while cognitive reappraisal (processing and reframing emotions) is associated with greater wellbeing.
Resilience in sports: a multidisciplinary, dynamic, and personalized perspective Taylor & Francis (2022) — International Review of Sport and Exercise Psychology https://www.tandfonline.com/doi/full/10.1080/1750984X.2022.2039749 Conceptualises resilience as a dynamic process of bouncing back from stressors rather than a fixed trait. Argues that durable resilience involves processing and recovering from difficulty, not simply withstanding it, with direct implications for how mental toughness is understood and developed in young athletes.
The sporting resilience model: A systematic review of resilience in sport performers PMC / PubMed Central (2023) https://pmc.ncbi.nlm.nih.gov/articles/PMC9811683/ A systematic review of how psychological resilience is conceptualised and developed in sporting contexts. Finds that resilience is built through repeated exposure to adversity combined with appropriate social support and processing, not through suppression or avoidance of difficult emotions.
Self-regulated learning and expertise development in sport: current status, challenges, and future opportunities International Review of Sport and Exercise Psychology (2018) https://www.tandfonline.com/doi/abs/10.1080/1750984X.2017.1381141 A comprehensive review establishing self-regulated learning as a critical factor in athletic development. Found that the ability to accurately monitor, evaluate, and adjust one’s own performance is one of the key variables distinguishing athletes who reach higher competitive levels from those who plateau, across both individual and team sports.
Self-Regulated Learning Assessment in Young Soccer Players: Beyond Competitive Levels PMC / PubMed Central (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC11614457/ Found that reflection on previous performance, specifically the capacity to honestly assess what went right or wrong, was the primary factor distinguishing higher-level from lower-level young athletes. Elite players invested significantly more effort in honest self-evaluation than their less-developed peers.
On the self-regulation of sport practice: Moving the narrative from theory and assessment toward practice PMC / PubMed Central (2023) https://pmc.ncbi.nlm.nih.gov/articles/PMC10086193/ Reviews how self-regulated learning shapes the quality of practice in sport. Athletes who engage in deliberate self-monitoring, planning, and reflection improve more rapidly than those who simply accumulate training hours without honest self-appraisal.
Get Excited: Reappraising Pre-Performance Anxiety as Excitement Alison Wood Brooks, Harvard Business School (2014) https://www.hbs.edu/ris/Publication%20Files/xge-a0035325%20(2)_0287835d-9e25-4f92-9661-c5b54dbbcb39.pdf The landmark study establishing that the physiological sensations of anxiety and excitement are neurologically identical. Found that individuals who reappraised their pre-performance arousal as excitement rather than trying to calm down performed significantly better, and that this shift required only a minimal cognitive change rather than a physiological one.
Emotional profile of athletes before competition: contributions for perceived stress, cognitive appraisal and coping strategies Frontiers in Sports and Active Living (2025) https://www.frontiersin.org/journals/sports-and-active-living/articles/10.3389/fspor.2025.1636826/full A study of 383 elite athletes finding that it was not the intensity of pre-competition emotions but rather the athlete’s interpretation of those emotions that predicted adaptive coping and performance outcomes. Athletes who viewed their arousal as facilitating performance showed greater perceived control and more adaptive responses than those who viewed it as threatening.
Sport-related anxiety: current insights PMC / PubMed Central (2017) https://pmc.ncbi.nlm.nih.gov/articles/PMC5667788/ A clinical overview of how pre-competition anxiety affects performance, emphasising that the individual’s cognitive appraisal of their arousal state is the key variable. Whether the same physiological sensations help or harm performance depends on the story the athlete tells about what those sensations mean.
Parents’ social comparisons and adolescent self-esteem: the mediating effect of upward social comparison and the moderating influence of optimism Frontiers in Psychology (2025) https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2025.1473318/full Examines how parental social comparison behaviours affect adolescent self-esteem. Found that comparing a child unfavourably to peers produces a contrast effect that tends to generate negative self-evaluation rather than motivation, particularly in adolescents who are still forming their sense of self.
The sporting resilience model: A systematic review of resilience in sport performers PMC / PubMed Central (2023) https://pmc.ncbi.nlm.nih.gov/articles/PMC9811683/ A systematic review establishing that psychological resilience in athletes is built through the experience of navigating adversity, not through being shielded from it. Found that resilience develops through the correct combination of environments, relationships, and the opportunity to encounter and overcome difficulty with appropriate support.
Exploring the behavioral indicators of resilience in professional academy youth soccer Taylor & Francis (2024) https://www.tandfonline.com/doi/full/10.1080/10413200.2024.2361701 Examines how resilience manifests in the behaviours of young elite soccer players navigating performance setbacks. Found that the capacity to maintain functioning under pressure is built through repeated exposure to challenges that require athletes to find their own way through, not by having those challenges absorbed by others.
Empowering young athletes: the influence of autonomy-supportive coaching on resilience, optimism, and development Frontiers in Psychology / PMC (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC11750835/ A time-lagged study demonstrating that autonomy-supportive coaching directly predicts resilience and optimism in young athletes, which in turn predict overall development. Found that coaching environments that give athletes ownership of their own experience produce more durable psychological resources than directive or controlling approaches.
Youth athletes’ perspectives on developmental influences of relationships in individual and team sports Taylor & Francis (2024) https://www.tandfonline.com/doi/full/10.1080/23311886.2024.2392023 Semi-structured interviews with 20 youth athletes finding that coach relationships shaped not just athletic performance but self-competence, motivation, and participation decisions. Athletes across both individual and team sports consistently identified the coach as one of the most influential relationships in their sporting experience, for better or worse.
Recovery self-regulation in sport: Theory, research, and practice SAGE Journals (2020) https://journals.sagepub.com/doi/10.1177/1747954119897528 Establishes that full recovery after competition requires both physical and mental restoration. Found that cognitive detachment and mental rest between competitions are necessary for the processing and learning that makes subsequent performance possible, with clear implications for when analytical conversations with athletes are likely to land.
Why do students drop out of regular sport in late adolescence? A systematic review PMC / PubMed Central (2024) https://pmc.ncbi.nlm.nih.gov/articles/PMC11684458/ A systematic review identifying the multiple distinct reasons young athletes leave sport, including burnout, motivational dips, genuine change of interests, and desire for environmental change. Each category requires a different response, and treating all expressions of wanting to quit as the same problem consistently produces the wrong one.
The Dropout From Youth Sport Crisis: Not as Simple as It Appears Kinesiology Review (2024) https://journals.humankinetics.com/view/journals/krj/13/3/article-p345.xml A critical review challenging the assumption that all youth sport dropout is a negative outcome requiring intervention. Found that at times, disengagement may be a protective and developmentally appropriate response to harmful environments, and that differentiating between types of disengagement is essential before any response is offered.
Burnout and dropout associated with talent development in youth sports Frontiers in Sports and Active Living (2023) https://www.frontiersin.org/journals/sports-and-active-living/articles/10.3389/fspor.2023.1190453/full Reviews the relationship between burnout and dropout in youth sport. Found that the primary perceived reasons for dropping out were lack of support from coaches, excessive pressure to succeed, and loss of connection with peers, all of which point to environmental factors that can be addressed before an athlete reaches the decision to leave.
Applying Social Cognitive Theory in Coaching Athletes: The Power of Positive Role Models Connolly, G.J. — Strategies: A Journal for Physical and Sport Educators (2017) https://www.researchgate.net/publication/316712708_Applying_Social_Cognitive_Theory_in_Coaching_Athletes_The_Power_of_Positive_Role_Models Applies Bandura’s social cognitive theory directly to coaching, finding that coaches who model desired behaviours have a greater developmental impact on athletes than those who only instruct them. Athletes learn emotional regulation, accountability, and standards by observing how coaches behave under pressure, not by listening to what coaches say about them.
A triadic comparison of the use of observational learning amongst team sport athletes, coaches, and officials ScienceDirect (2010) — Psychology of Sport and Exercise https://www.sciencedirect.com/science/article/abs/pii/S1469029210001433 One of the few studies comparing observational learning across athletes, coaches, and officials. Found that coaches use observational learning most frequently for skill and strategy, and that modelling is a central mechanism through which sport environments transmit behaviours and norms across generations of athletes.
How do goal orientations and motivational climate interact to affect short-term performance and self-confidence in sport? Taylor & Francis (2024) https://www.tandfonline.com/doi/full/10.1080/10413200.2024.2428649 Across three experiments, athletes with a task orientation showed more stable performance and higher self-confidence than those oriented toward ego-based goals, particularly in precision tasks under pressure. Ego-oriented athletes showed performance vulnerability when outcomes were threatened, while task-oriented athletes maintained a more consistent internal anchor.
Developing and training mental toughness in sport: a systematic review and meta-analysis PMC / PubMed Central (2020) https://pmc.ncbi.nlm.nih.gov/articles/PMC7299040/ A systematic review of interventions designed to develop mental toughness, finding a large overall effect for psychological training programmes targeting MT. Concludes that mental toughness is a trainable resource rather than a fixed personality trait, with deliberate practice and structured environments as the key development mechanisms.
Developing Mental Toughness: Lessons from Paralympians Frontiers in Psychology (2017) https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2017.01270/full An interpretive phenomenological study of ten Paralympians finding that mental toughness developed through exposure to demanding situations within a supportive environment. Athletes consistently identified their environments, relationships, and experiences of overcoming specific challenges as the source of their psychological resources, not innate character.
